I am trying to make a copy of ultimate spiderman and when i open it up in explorer there is a file that is called dummy.dat and it is 2.38Gb. Does this file have to be removed in order for a backup to work? I made a 1-1 copy with nero 6 and the game freezes at the intro. I used a TDK 8x DVD-r at 4x. I rad somewhere if you use the dvd decryptor, apache, cd-gen method it can fix this. Any clue?

you have to overwrite those files as the file says they are dummy files these files prevent the game from loading here is guide:



Dummy Files:
Some games have dummy files in them. They are used to increase the
size of the image and to copy-protect the game. Burning games with the
dummy files left unchanged will result in a game that does not boot
(using swap magic anyway). To remedy this annoyance follow these fun
steps.

2) Create a new text file. Open it and press the space
bar, then close it. This creates a byte of data in the text file.

3) Rename the text file you made to the exact same name
as the dummy file in your folder. The dummy file will be called
something like DUMMY.DAT, DUMMY.000, DUMMY.001 etc, GARBAGE.DAT. These
files will always be in the main folder of the iso.

4) Overwrite all those dummy files with the blank ones
you've created. (Games generally only have 1 dummy file, but some have
multiple dummy files)


hope this helps

I used DVD Decrypter to just make an iso and it works fine. Is it possible that at some point in the game the game will freeze because I left it in? I have that problemwith alot of recent backups and i never have booting problems..... I dont think its my ps2 as these discs will freeze at same point in gmae on his.
